Between the bearing (ball) cover of axle and labyrinth cover, be provided with the first gap, be provided with first group of circular groove and second group of circular groove in the first gap, first group of circular groove is arranged on labyrinth and covers, and second group of circular groove is arranged on bearing (ball) cover or labyrinth covers; The bearing (ball) cover relative with first group of circular groove is provided with toroidal cavity, the first through hole is provided with between toroidal cavity and chamber, first group of circular groove is connected with chamber with the first through hole by toroidal cavity successively, and the quantity of first group of circular groove and second group of circular groove is 2-5.
The preferred technical solution of the present invention is that the both sides of above-mentioned first through-bore axis are respectively arranged with the second through hole and third through-hole, second through hole is all connected with toroidal cavity with third through-hole, the axis of the axis of the first through hole and the axis of the second through hole and third through-hole all with the axes normal of described axle, the axis of the first through hole and the axis of the second through hole and the axis angle of third through-hole are 30 degree-60 and spend.
The angle of above-mentioned first through hole and the second through hole and third through-hole is 45 degree.
The angled end of above-mentioned first through hole, the second through hole and third through-hole is all connected in same port, and the first through hole, the second through hole are connected with toroidal cavity by described port with third through-hole.
The cross section of above-mentioned first through hole, the second through hole and third through-hole is circle, and the diameter of the first through hole, the second through hole and third through-hole is all less than the width of toroidal cavity.
The quantity of above-mentioned first group of circular groove and second group of circular groove is 3-4.
The present invention has the following advantages:
Labyrinth of the present invention lid, bearing (ball) cover are designed with two groups of circular grooves, and these two groups of ring channel structures are simple, convenient processing and manufacture, cover the toroidal cavity structure between bearing (ball) cover, effectively prevent the leakage of lubricant oil by labyrinth.
In addition, the present invention to the hardness of bearing (ball) cover and surface roughness requirements not high, labyrinth lid axial activity less, thus stability of the present invention is higher.By simple structural design, reach sealing effect, reduce difficulty of processing, save cost of parts and maintenance cost.

Fig. 2 is the A-A direction view of Fig. 1;
Fig. 3 is the vibrator sealed structural representation of prior art;
Reference character: 1-axle; 2-labyrinth is covered; 3-bearing (ball) cover; 4-disc; 5-first through hole; 6-chamber; 7-circular groove; 8-toroidal cavity; 9-second through hole; 10-third through-hole.
Embodiment
As shown in Figure 1, the invention provides a kind of vibrator sealing configuration, comprise axle 1, labyrinth lid 2, bearing (ball) cover 3, disc 4 and casing, the periphery of axle is socketed with disc and labyrinth lid respectively, the periphery of labyrinth lid is socketed with bearing (ball) cover, and equal interference fit between axle and between disc and axle is covered in labyrinth; Bearing (ball) cover is fixed on casing and between disc and labyrinth lid, is provided with chamber 6 in casing.
The bearing (ball) cover of close axle and labyrinth are provided with the first gap between covering, and as Fig. 1, there is the second gap between bearing (ball) cover and the disc in left side; Be provided with first group of circular groove 7 and second group of circular groove in first gap, first group of circular groove is arranged on labyrinth and covers, and second group of circular groove is arranged on bearing (ball) cover or labyrinth covers; The bearing (ball) cover relative with first group of circular groove is provided with toroidal cavity 8, is provided with the first through hole 5, first group of circular groove and is connected with chamber with the first through hole by toroidal cavity successively between toroidal cavity and chamber.
Bottom of the present invention is provided with attachment face, and during vibrator works, the general and horizontal plane of the attachment face of bottom keeps 30 degree of-60 angle of spending, preferably 45 degree.In order to meet different matching requirements, first through-bore axis is vertical with the attachment face bottom the present invention, see Fig. 2, the both sides of the first through-bore axis are also respectively arranged with the second through hole 9 and third through-hole 10, second through hole is all connected with toroidal cavity with third through-hole, the axis of the axis of the first through hole and the axis of the second through hole and third through-hole all with the axes normal of axle, the axis of the first through hole and the axis of the second through hole and the axis angle of third through-hole are 30 degree-60 and spend, preferably 45 degree.
During vibrator works, generally attachment face and horizontal plane are kept 45 degree of angles, now, the axis of the second through hole or the axis of third through-hole and horizontal plane, now, be in best leak position with the through hole of horizontal plane.
Usually the cross section of the first through hole, the second through hole and third through-hole is set to circle, the diameter of the first through hole, the second through hole and third through-hole is all less than the width of toroidal cavity.
See Fig. 1, v shaped ring is also equipped with between covering in bearing (ball) cover and labyrinth, when axle drives labyrinth lid to rotate, because the chamber of casing is built with lubricant oil, lubricant oil a small amount of in chamber can enter into the first gap by the second gap between bearing (ball) cover and the disc in left side, then toroidal cavity is entered into, cover because first group of circular groove is arranged on labyrinth, therefore, first group of circular groove also can rotate along with the rotation of axle, under the turning effort of first group of circular groove, stick to lubricant oil on first group of circular groove under the influence of centrifugal force by the first through hole, second through hole and third through-hole flow out, in toroidal cavity, the minimizing of oil mass makes toroidal cavity internal pressure reduce, the lubricant oil being positioned at second group of circular groove on the second gap on the left of toroidal cavity and right side will be inhaled into toroidal cavity, and then by the first through hole, second through hole and third through-hole are thrown out of, iterative cycles like this.
First group of circular groove quantity is 2-5, preferred 3-4, an annular tooth is formed between two circular grooves, annular tooth quantity is more, the pressure that during work, toroidal cavity produces is lower, lubricant oil unnecessary in gap just can enter toroidal cavity, enters chamber eventually through the first through hole, the second through hole and third through-hole.
For the ease of processing the present invention, the angled end of the first through hole, the second through hole and third through-hole is all connected in same port, and the first through hole, the second through hole are connected with toroidal cavity by described port with third through-hole.
Above sealing principle, makes lubricant oil repeatedly be got rid of into casing in the passage leaked, achieves the sealing to lubricant oil by mechanical structure, reach best sealing effect.
